Secunia Security Advisory – Jason Hoover has discovered a vulnerability in MigrationTools, which can be exploited by malicious, local users to disclose potentially sensitive information or to perform certain actions on a vulnerable system with escalated privileges. The vulnerability is caused due to the nis.$$.ldif temporary files being created insecurely in /tmp. This can be exploited via symlink attacks to overwrite arbitrary files with the privileges of the user running the migrate_all_online.sh script. The temporary files are world-readable are not deleted if ldapadd fails. This may disclose sensitive information such as users’ password hashes. The vulnerability has been confirmed in version 46. Other versions may also be affected.
